Embodiment Construction

[0036] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0037] With the popularity of smart devices with dual operating systems, more and more software is carried in the smart devices with dual operating systems. When there are many running software, there is a problem of non-matching of each software. At this time, directly applying the memory management method of the single operating system to the du...

Abstract

The invention provides a dual system-based memory management method and apparatus. The method comprises the steps of receiving an operation system switching instruction input by a user; according to the operation system switching instruction, determining a first operation system running in a foreground and a second operation system running in a background; and setting a first maximum occupied memory for the first operation system, and setting a second maximum occupied memory for the second operation system, wherein the first maximum occupied memory is greater than the second maximum occupied memory. According to the dual system-based memory management method provided by the invention, the maximum occupied memory for controlling the operation system is changed due to difference of the operation system running in the foreground and background, so that the operation system running in the background is prevented from occupying an excessive memory, the memory utilization rate is increased,the software running fluency of the operation system running in the foreground is improved, and the memory management effect is improved.

Description

technical field [0001] The invention relates to the field of computers, in particular to a memory management method and device under dual systems. Background technique [0002] With the development of computer technology, R&D personnel have developed more and more software that can run on smart terminals such as mobile phones and computers, so as to provide convenience for users' daily life and work. However, due to limited resources such as memory, central processing unit (Central Processing Unit, CPU), and memory of the smart terminal device, the more software runs in the smart terminal, the smoother the running of the software may be reduced. [0003] In order to ensure smooth running of the software, a memory management module is usually installed in the smart terminal to make full use of the physical memory. The memory management module divides the processes running in the system according to their importance. And when memory resources are tight, automatically kill le...
